Description
Technical field
The utility model relates to a kind of generator cooling heat dissipation double-sucking type centrifugal blower, is applicable to the cooling heat dissipation of high-rating generator, belongs to field of fluid machinery.
Background technique
Generator is because of its work characteristics long-term, that move continuously, and inner meeting produces a large amount of heats, in order to make heat be scattered and disappeared in time, must have a set of complete heat radiation cooling system.Because the heat yield of generator is higher, so its air-air cooler load carrying is heavier, very high to the traffic demand of cooling-air.The cooling air quantity of existing generator must reach 5m
3/ s is above could meet heat radiation requirement, by calculating, blower fan specific speed is far beyond the scope of single-stage centrifugal fan, according to theory, recommend to need to adopt propeller fan just can meet the demands, but on the other hand, according to as installed situation and intake type, propeller fan cannot meet the demands, meanwhile, according to the radiating requirements of generator, select single-stage centrifugal fan to be difficult to meet this traffic requirement.
Summary of the invention
the purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure,efficiently, greatly
flow andlow noise generator cooling heat dissipation double-sucking type centrifugal blower.
The utility model
technological scheme be:a kind of generator cooling heat dissipation double-sucking type centrifugal blower, comprise spiral case, guide-ring, impeller, scaffold, motor, slip ring and hasp, it is characterized in that the impeller in described double-sucking type centrifugal blower is double-sided impeller, this double-sided impeller is comprised of wheel hub, rear trochal disc, blade and front wheel disc; Be that double-sided impeller is designed to left and right two-part and both sides air intake type structure, double-sided impeller is provided with two groups of blades, i.e. left side blade, right side blade; These two groups of blades all adopt the backward wing blade blade of high-efficient low-noise, have both met the performance requirement of whole blower fan, and efficiency and noise have also obtained further optimization; Two groups of blade blades are welded on rear trochal disc by symmetric form, and double-sided impeller is fixed on motor-shaft extending end with the form of the additional baffle plate of the axis of cone;
Described spiral case is divided into two-part, and a part is how much spiral form structures of standard, and another portion is half-cone diffusion formula structure; Cooling-air completes water conservancy diversion and diffusion in first portion, and while flowing through second portion, along with the increase gradually of discharge area, flow velocity reduces, and a part of dynamic pressure will be converted to static pressure, and fan outlet static pressure obviously improves.
Described guide-ring is divided into two kinds of cascade-types, and leaf grating one and leaf grating two, two leaf gratings are by reasonable selection and being arranged in spiral case; Make exit flow in the situation that reducing resistance as far as possible can obtain uniform distribution, be more conducive to the heat radiation of cooler.
Described slip ring, for cone arcuate structure, is bolted and is fixed on spiral case outer panel; Reduced flow losses on the one hand, improved efficiency, by improving the entrance flow condition of air-flow, also made the aerodynamic noise of whole blower fan obtain reduction in addition.
Described scaffold is installed on matrix by bolt, and motor is fixed on scaffold by the mounting hole on base;
Described double-sucking type centrifugal blower is fixed on generator one side by six M16 hex head bolts, is vertically hung on air-air cooler bottom by four hasps simultaneously.
The utility model is the double-impeller centrifugal formula ventilator structure of a kind of higher specific speed, large flow.By the mode from spiral case two sides air intake, the flow of single-stage impeller is dropped to original half, the utility model designs based on this just.
Impeller in this double-sucking type centrifugal blower adopts double-sucking type structure, be that impeller is comprised of left and right two-part, during work, intake method is both sides air intake, in the situation that other operating conditions are constant, compare with single impeller structure, flow is significantly improved, thereby more can meet customer need, also making the using scope of this blower fan obtain widening significantly, is a kind of improvement and bring new ideas.This cooling fan blade adopts backward wing blade blade, has guaranteed on the one hand also to make noise obtain control to a certain degree by higher pneumatic efficiency simultaneously.At fan outlet place, because connect cooler size is larger, in order to guarantee the relative homogeneity of exit flow and the heat radiation of the balance of cooler, adopted the built-in guide-ring of impeller outlet and how much traces of spiral case outlet along the design of snail linguoclination, the former has promoted the uniformity of exit flow in lower pressure loss situation, the latter had both met the interface requirement with cooler on the one hand, played to a certain extent again diffusion action, both combinations, make the performance of whole ventilator and use occasion greatly be better than other ventilators of the same type.Whole ventilator structure is moderate, be bolted with the mode of vertical hanging and install, the slip ring that cooling-air is installed via level enters blower fan inside, after vane rotary pressurization, with the flow path direction that goes out vertically upward, to enter air-air cooler inner, and then cooler each several part is blown cooling, guarantee the normal operation of cooler and even whole generator system.
This double-sucking type centrifugal blower is applied to generator heat-radiation cooling system, and it not only needs to meet the heat radiation requirement of generator, is also bearing the task of whole system noise reduction simultaneously, therefore the noise of ventilator has been proposed to higher requirement.It is the once innovation of centrifugal blower in the heat radiation of large industry equipment cooling system that cooling fan is applied in generator cooling system.
In sum, the utility model is compared with tradition ventilator of the same type, has the features such as efficient, large flow, low noise.
